Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If destructive sampling is used to analyze optical isomerism, then measurement precision is improved, but loss of substance increases and productivity decreases
Solution Approach 1:
The patent replaces destructive mechanical sampling with non-destructive optical measurement using a sensor unit that detects optical isomerism through light interaction. This substitution allows analysis without consuming the sample material, resolving the contradiction between measurement precision and substance loss.
Solution Approach 2:
The patent introduces an optical measurement system as an intermediary between the chemical reaction system and the analysis process. The sensor unit acts as a mediator that extracts information about optical isomerism without directly contacting or consuming the reactants, enabling non-destructive analysis.
2Productivity
If non-destructive optical analysis is implemented, then loss of substance is reduced and productivity is improved, but device complexity increases
Solution Approach 1:
The sensor unit is designed to perform multiple functions: it measures optical isomerism, monitors reaction progress, and provides data for control decisions. This multi-functionality reduces the need for separate measurement and control systems, thereby reducing overall device complexity while maintaining high productivity.
Solution Approach 2:
The optical analysis system is integrated directly into the reaction apparatus, allowing the system to self-monitor and self-regulate. The sensor unit continuously provides feedback without requiring external sampling or analysis equipment, enabling the system to serve itself and reducing operational complexity.
3Loss of time
If real-time monitoring is implemented, then productivity is improved and loss of time is reduced, but device complexity and use of energy increase
Solution Approach 1:
The system implements periodic or continuous optical measurements at key reaction stages rather than constant high-energy monitoring. The control apparatus processes data at intervals necessary for decision-making, reducing energy consumption while maintaining real-time responsiveness and minimizing time loss.
